Anti -corrosion steel pipe is a new type of steel pipe. After anti -corrosion treatment, it can effectively prevent or slow down the corrosion of chemical or electrochemical reactions during transportation and use; , Especially in the cold winter, do you know what the preservation method of anticorrosive steel pipes is?
In fact, there are many thermal insulation methods for anticorrosive steel pipes, including coating thermal insulation coatings, wrap the anticorrosive material around the anticorrosive steel pipe, and fill and thermal insulation for anti -corrosion steel pipes. Specifically, they are:
1. The anticorrosive steel pipe is insulated by coating the insulation coatings, that is, using the insulation material such as expansion perlite, expanded frog stone, asbestos, asbestos, diatomic soil cooked materials, etc., and then add cement, water glass , Refractory binder (such as clay) or condenser (such as sodium fluorosilicate), then add water and mix uniformly according to a certain percentage to form mud -shaped, or nake these insulating materials on your hands or apply it on anticorrosive steel pipes to tools and tools The insulation method of this anticorrosive steel pipe is also called coating insulation.
2. The anticorrosive steel pipe is insulated by the insulation material of the package, that is, the insulation materials such as slag felt, glass cargo, grass rope, asbestos, or cotton belt are directly wrapped in order to not worry that the anticorrosive steel pipe is frozen and ruptured. It does not affect the use of anticorrosive steel pipes.
3. The filled material in the anti -corrosion steel pipe can be filled with insulation materials, that is, when the thermal insulation material is a block material, it can also be filled with insulation; The same layer, then use iron, aluminum or wire mesh to wrap the support ring, and then use insulation material insulation; material filling; filling method can also be made of rigid arc blocks made of prefabricated porous materials as support structure, with a distance of about 900 mm According to the shape size of the pipeline insulation layer, the iron wire mesh of the flat woven stab was cut, and the winding machine was processed into a circular shape, covering the slag wool on the support ring, and then filled with the insulation structure with a metal protective shell.
4. In addition, we can also use prefabricated thermal insulation treatment of anticorrosive steel pipes to keep insulation. The main materials of prefabricated thermal insulation products are foam concrete, asbestos, diamond cotton, glass wool, rock wool, expanded perlite, swelling Ver stone stone , Calcium silicate, etc.; prefabricated pipeline insulation structure, usually DN ≤ 80 mm in diameter, uses a semi -circular case, such as DN≥100 mm, using a fan -shaped tile (arc -shaped tile) or trapezoidal tile.
Well, the above is the introduction of the thermal insulation method of anticorrosive steel pipes. Generally, there are four main insulation methods for anticorrosive steel pipes, but different thermal insulation methods have different insulation measures; therefore, everyone is conducting the insulation treatment of anticorrosive steel pipes. At this time It is necessary to choose a suitable insulation method to help the corrosion steel pipe go smoothly to winter!
